To submit a lost property claim for items left at the airport (boarding gates, controls, etc.), contact the lost and found office at the airport in question. Please check the airport website for the contact details.

Iberia only processes lost property claims for items left on its planes, in the VIP and UM lounges, or on the buses that take you to/from the plane. For items left on a plane operated by another airline, we advise you to contact the customer service department of the airline in question. You can search for lost property from the second day after you left it behind.
Iberia cannot be held responsible for the loss of items left on board its planes.
